Several masses of condensed chromatin without nuclear membrane were observed in some treated K562 cells,while chromatin of some other cells tended to marginate in crescents around the nuclear envelope with compacting cytoplasm,normal or slightly expanded endoplasmic reticulum,which presented typical morphology of apoptosis.

电镜下，加药处理组中部分细胞染色质凝集成块，没有核膜包被，部分细胞染色质靠核膜边集呈新月形，胞浆浓缩，内质网结构正常或有扩张，呈现典型的凋亡细胞形态。

The gold-labelling granules of FGF receptor appear on the day 8, but very little in number. NGFR appear on the day 9 and they are located in cell membrane, cytoplasm, endoplasmic reticulum, nuclear membrane and nucleoplasm.

第8d可检测到少量散在的FGFR金标颗粒，TrkA于第9d出现，随着胚胎的发育，金标颗粒逐渐增多，主要定位于细胞膜、胞质的基质、内质网、核膜及胞核中。

Tapetum cells degenerated and only ER small vesieles were the visible organelle at the 2—celled pollen stage.

绒毡层在小孢子液泡化中期开始退化，开始退化的绒毡层表现为内质网腔膨大，核周腔增大，核孔数增加。

The results indicated that the erythropoietic/granulopoietic ratio was markedly increased with megaloblastic morphology in all stage of erythrocyte.

结果表明：2例CDAⅠ型患者骨髓幼红细胞比例增加，各阶段细胞存在不同程度巨幼样变；原红细胞核不规则，早幼或中幼红细胞可见奶酪核，约半数晚幼红细胞有核溶解和破碎现象，晚幼红细胞核损伤有时伴胞质溶解，细胞间染色质桥少见；各阶段红细胞核膜和内质网同时出现不同程度溶解。

Under electron microscope, tumor cell emerged karyopyknosis, new-moon shaped or circular, nucleus membrane was clesr, endoplasmic reticulum was dilated, and mitochondrion was swollen. A lot of apoptosis cells emerged in the tumor foci under light microscope.

光镜下显示肿瘤灶中出现许多凋亡细胞；肿瘤组织电镜观察，瘤细胞核染色质浓集成块，在核膜内呈新月形或环形排列，核膜清楚，瘤细胞内质网扩张，线粒体肿胀。

Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.

结果：倒置显微镜和透射电镜观察显示，经SAHA处理的细胞增殖速度显著减慢，细胞体积增大，细胞核较小，形状较为规则，核仁数量减少、体积变小，核内常染色质增多而异染色质减少，核质比例减小，细胞质内线粒体数量增多、线粒体嵴发达，高尔基体较为典型，粗糙型内质网增多，呈现出与正常上皮细胞相似的形态变化；MTT比色法测定结果显示不同浓度(2.5、5.0、7.5、10.0uM)SAHA对SMMC-7721细胞的增殖均有抑制作用，并有明显的剂量依赖和时间依赖关系；免疫细胞化学检测显示SAHA能显著降低PCNA和AFP在SMMC-7721细胞中的表达；流式细胞仪检测结果显示，SMMC-7721细胞经SAHA处理后，G0/G1期细胞明显增加，S期细胞则明显减少，细胞被阻滞于G0/G1期；RT-PCR检测结果表明，SAHA作用12h后SMMC-7721细胞中p21WAF1 mRNA的表达即有增加，24h后更为明显。

At mononucleus microspore stage,cytoplasm were thick and organella,such as mitochondria,endoplasmic reticulum were abundant.At two\|nucleus and three\|nucleus stage,there were a lot of starch grains.

结果表明，85 EA、89 AR、TA 与恢复系杂交F1 代小孢子发育表现出明显的可育特征：在单核期，细胞质浓，细胞器丰富，线粒体、内质网等十分发达，二核及三核期淀粉粒数量多。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。
